Brian Bailey Preface to the Revised Edition

WooHoo for WuFoo!

WuFoo is wonderful. What is it? A dead simple way to create online forms. A number of sites offer a similar service, but I've never found one this well done and fun to use. The forms can be embedded on your site or you can link directly to the hosted version. Plus, the website, design, and copy writing are first-class, too. Check out some examples of what you can do with WuFoo. Highly recommended!

Take a look at Form Assembly if you want to compare your options.
